Abstract

Abstract:

Outpatients in a 3A (Grade A) Hospital in Nanchong City have been randomly selected. According to the EP-6A2 document announced by CLSI, the precision, linear range and accuracy of μTASWakoi30 have been verified by combining alpha-fetoprotein (AFP) and its heterogeneity ratio (AFP-L3) with abnormal prothrombin (PIVKA-Ⅱ) reagent specification. The results showed that the precision CV of μTASWakoi30 was below 10%, and the precision of AFP and PIVKA-Ⅱ were all below 10%, and AFP and PIVKA-Ⅱ were fitted well by the regression of mean value and predicted value in different proportion of high value samples. The recoveries were within 80%~120% at different calibration levels and the accuracy was high.

Key words: electrophoretic fluorescence immune-analyzer, AFP, PIVKA-Ⅱ, performance verification
